Same experience for me. The University of Washington headache clinic recommended Vitamin D and Magnesium supplements and it made a marked difference in my mood. Turns out having constant mild headaches is pretty depressing.

Have to be careful with magnesium, too much and you'll spend the entire day on the toilet been reminded that topologically humans are a tube.

This effect is more pronounced with lower-quality magnesium supplements, such as magnesium oxide, magnesium sulfate, and magnesium chloride. These compounds are insoluble in water (magnesium oxide), or their counter-ions are not absorbed (magnesium sulfate). Magnesium + glycine (specifically bisglycinate which is the magnesium salt with two glycine molecules) is more bioavailable and does not have a laxative effect since glycine is easily absorbed by cell walls. Magnesium citrate also does not have a marked laxative effect and is more bioavailable than magnesium oxide, but less bioavailable than magnesium bisglycinate.

Thank you for the info, I'll check those out, my medication is thought to affect nutrient levels so I take supplements (I found out about the laxative effects myself..)
